[Asterisk-Dev] PTHREAD_MUTEX_RECURSIVE

[Sam Bingner]

You have to look at features.h

#ifdef  _GNU_SOURCE
# define __USE_GNU      1
#endif

Then if you look in pthread.h for __USE_GNU you find it a billion places.
It's the same on every version I've seen so far, including redhat 9.

Perhaps that's a difference between redhat and others? _GNU_SOURCE doesn't
appear in pthread.h on redhat 9.

Cheers,
Rich
